Hi all,
Just a quick update, as it’s been two weeks since the last major prune. All seems to be filling out nicely, but I do need you advice on a few things. Sorry this is going to be a list but saves you having to read all my waffle!
i) I have noticed the HM and HC, whilst growing well (they are both quite thick) are getting what can only be described as black leaves. I think they are the older leaves, especially on the HM. Is there anything I can do about this or is it just the older leaves dieing off? Also, should the HM be pruned and replanted like a stem plant or should I just cut it right back every now and then to get new growth from the base?
ii) The P. helferi is growing a bit too well, the pics don’t really show it but its getting leggy with long stems. In growing fast it’s also pulling the HC around it out of the substrate. Thinking of removing it completely? Or should I prune hard to encourage shorter growth? Zig?
iii) I have every sort of algae under the sun in there at the moment; BGA, Hair, thread and green stop. Any advice would be very much appreciated. None of them are at present unmanageable, but here are my own thoughts on possible solutions.
Hair - I only have 3 shrimp in there, should I add another 4/5?
Thread - this seems to only be on the glass so it gets removed each week during the clean, but if I could prevent it that would be best, of course. Would more shrimp also help with this?
Green spot - it seems to only be on the crypts at the moment. I don’t have any ottos or sucker mouth catfish as there isn't the space really, but I could add one or two ottos at a push? Or is there something else I can do?
BGA - I don’t know what to do about this one. I could go down the blackout route, but this doesn’t really address the cause. The water flow in the tank is very slow but I could increase this using a spray bar (although that'll just mean another piece of kit in the tank, something I’m trying to keep to a minimum).
Anyhoo please advise if you can, it would be good to sort this before it gets out of hand. Current tank stats below, I would add the CO2 has been off over the weekend as I was away and it stopped (Dam JLB regulators!).
pH - 7.0 (this is normally around 6.8 but the problems with the CO2 allowed it to rise)
CO2 - 30ppm (I try to keep this on the high side so is often between 30 - 40ppm)
NO3 - 20 (again trying to keep this at 20ppm, often higher)
NO2 - 0
NH3 - 0
PO4 - 2
KH - 6
GH - 7
And now the pics, sorry to keep on, hope you're not bored!
Top of the tank so you can see the HM, it looks much better from the top IMO, that’s the trouble with such a short tank!
Full tank - I removed the arch, any views on how it looks without it? Better/worse? It is a very big feature in the tank, thinking perhaps too much of a feature?
Full tank - including the arch

Close up of moss - no real change, this stuff grows really slowly!
